It's a very curious thing that happened with my barred rocks. I got 3 straight run chicks in May and by a few weeks of age, it looked like 2 were pullets and one roo. The "girls" feathered early, had narrow bars, dark smudges on their legs and tails that were different from the slower feathering, larger chick. He took forever to feather but grew a large red comb, had large waddles and really long upright tail feathers by 3 months old. Very thick yellow legs. But then one day, I heard 2 birds crowing....one was my favorite "pullet". She didn't sound as good as the rooster but within couple weeks was really good at it. And then the other one started crowing too. They are smaller than the "real" rooster but at 4 months started developing hackles,larger combs and waddles. One died unexpectedly, and the other looks identical to a rooster in every way now...saddle feathers too, only the posture is more hen-like than the other real rooster who stands very erect and he is much larger. Has anyone else experienced this? I guess I should just move the "hermaphrodite" bird to the rooster coop? Or is it ok to leave with other hens? One of my RIR hens has suddenly started to grow large comb now too and the Australorp getting large waddles. I'm nearly in panic mode that my flock is changing gender, although I think it's impossible!!
